Specifications of BCM5645B0IPB

• Lead Free Status / RoHS Status: Not Compliant

The BCM5645, with a forwarding rate of 8.9 Mpps, defines the next
generation of performance for 48-port Fast Ethernet switching solutions.
Through its advanced ContentAware™ feature set, the StrataSwitch II
product family supports advanced applications and services, at wire
speed, with non-blocking performance.
The BCM5645 uses 60 million transistors and 1 MB of internal memory
to integrate the functionality of large 48-port board designs into two
chips. This level of integration allows the BCM5645-based switch to
sustain line rate on all 48 Fast Ethernet and 2-Gigabit Ethernet ports for
Layer 2, and Layer 3 switching and all L2-L7 processing applications.
The StrataSwitch IITM Fast Filter Processor (FFP) delivers line rate
packet processing to support policy management, VoIP, and firewall
applications.
The data packet memory can be extended from 4 MB to 64 MB using
commodity SDRAM in either a 128-bit-wide interface or a 64-bit-wide
interface.

The BCM5645 also provides a wide range of choices in levels of
manageability and solution costs. For example, the BCM5645 provides
a low-cost I2C interface for unmanaged applications, as well as a 33-
MHz PCI interface for higher management and network service
requirements.
The flow metering and monitoring of the StrataSwitch II
new applications and services. ISPs can benefit from the metering
capabilities of the StrataSwitch II
from over-consuming their network. Using the monitoring features of
the FFP, IT managers can gain tremendous insight to the utilization of
their current network resources and optimize those resources
accordingly.
